Overview of this book

Snowflake is a unique cloud-based data warehousing platform built from scratch to perform data management on the cloud. This book introduces you to Snowflake's unique architecture, which places it at the forefront of cloud data warehouses. You'll explore the compute model available with Snowflake, and find out how Snowflake allows extensive scaling through the virtual warehouses. You will then learn how to configure a virtual warehouse for optimizing cost and performance. Moving on, you'll get to grips with the data ecosystem and discover how Snowflake integrates with other technologies for staging and loading data. As you progress through the chapters, you will leverage Snowflake's capabilities to process a series of SQL statements using tasks to build data pipelines and find out how you can create modern data solutions and pipelines designed to provide high performance and scalability. You will also get to grips with creating role hierarchies, adding custom roles, and setting default roles for users before covering advanced topics such as data sharing, cloning, and performance optimization. By the end of this Snowflake book, you will be well-versed in Snowflake's architecture for building modern analytical solutions and understand best practices for solving commonly faced problems using practical recipes.

Chapter 7: Secure Data Sharing

Traditional warehouse solutions share data by extracting the data out and sending it over transport mechanisms such as FTP and email. A downside to this is that as soon as the data is extracted, it is already out of date. Snowflake overcomes this by providing a unique data-sharing solution that ensures reduced costs, reduced operational overhead, and always provides up-to-date data.

This chapter details how to share data with other Snowflake customers as well as non-Snowflake customers.

The following recipes will be covered in this chapter:

  • Sharing a table with another Snowflake account
  • Sharing data through a view with another Snowflake account
  • Sharing a complete database with another Snowflake account and setting up future objects to be shareable
  • Creating reader accounts and configuring them for non-Snowflake sharing
  • Sharing an object with a non-Snowflake user
  • Keeping costs in check when sharing data with non-Snowflake...
